At 2:46 p.m. on September 16, 2024, Employee #1 (20) and Employee #2 (age unknown) were conducting inspections and maintenance on a tanker trailer previously used to transport propane. The tank was to be emptied using flaring, in which the remaining gas is vented through a hose to a large tripod “flare” device. The top of the flare is then ignited to burn the gas, rather than releasing it into the atmosphere. The hose that connected directly to the tank was attached correctly but not connected to the flare, causing propane to discharge onto the ground near the employees. Employee #1 went under the tank to grease the trailer with an electric-powered grease gun. It was suspected that the battery on the grease gun may have sparked, igniting the propane that had already filled the area, engulfing the employee in flames.
